| Résumé : |
A series of latex paints was prepared based on a range of commercially available rheology modifiers including cellulosic derivatives, polyacrylic alkali soluble and polyurethane associative thickeners with latives viz., small particle acrylic, large particle acrylic, styrene acrylic and vinuyl éacrylic latices. An extensive range of rheological, optical and physical properties was determined to evaluate the relative performance characteristics of each system. It was found that small particle acrylics latex coupled with associative thickeners offer superior stability, coverage, sag resistance, whiteness index, improved freeze-thaw stability, Gilsonite porosity test and ease of application pproperties. The large particle latices offer better whiteness index, opacity, minimun synerisis and inferior freeze-thaw stability. |
